The DF-72/EC is a high quality, photoelectric smoke detector with a built-in supervised digitally-coded radio transmitter. The DF-72/EC monitors and then transmits alarms, low battery, and test signals. The DF-72/EC sounds a local alarm as soon as smoke is detected. Twenty seconds after the local alarm sounds, the DF-72/EC’s transmitter will send an alarm signal to the console. The alarm signal will be repeated every 20 seconds as long as smoke is still present.
Coding switches are not required or used in the DF-72/EC. Each transmitter is pre-coded at the factory to a unique code. With the DX format, there are more than one million codes possible.
